Dual-Core Opterons Running Linux

"Dual-core CPUs are single physical processors that contain multiple processor cores. This means that, in theory, for the motherboard space of a single processor, you get the performance of dual processors.

Let's start this off by showing you the two ways that AMD and Intel implement their current workstation/server processors and how the processors speak to the rest of the system."Story
